Ship pipe installation process and pipe

Abstract

The invention discloses a ship pipe installation process and a pipe. The ship pipe installation process comprises the following steps: making a prefabricated pipe with one detachable connecting flangeon a manufacturing site; pre-hoisting the prefabricated pipe to the corresponding position on the ship to be pre-assembled; if the length of the prefabricated pipe is proper, hoisting the prefabricated pipe the manufacturing site to complete manufacturing; and hoisting the manufactured prefabricated pipe to the ship to finish installation. The prefabricated pipe is provided with a connecting flange fixedly connected at one end and the connecting flange detachably connected at the other end; whether the length size of the prefabricated pipe meets the actual field installation requirement or not can be effectively judged after preassembly; the length of the prefabricated pipe can be adjusted conveniently, such that a large amount of work caused by the fact that when the length of an existing prefabricated pipe needs to be adjusted or the position of the connecting flange needs to be adjusted, the connecting flange needs to be cut off and then welded again is avoided, and material wastecaused by the fact that the welded connecting flange cannot be used again is avoided.

Description

technical field [0001] The invention relates to the technical field of ship pipeline construction, in particular to a ship pipe installation process and the pipe. Background technique [0002] At present, there are mainly two ways to make pipes for ships under construction: prefabricated pipes and existing school pipes. Among them, the prefabricated pipes are pipes that have been manufactured in the infield workshop, and the flange ends and pipes have been welded in the infield, and can be directly hoisted to the ship for installation in the future, without on-site calibration. The flange end and the pipe of the current school pipe are not welded. It is necessary to carry out on-site calibration and assembly according to the equipment on board or the distance between the two ends of the pipe, and then take the pipe back to the infield workshop for welding. [0003] However, if the pipes are made into prefabricated pipes for installation during the shipbuilding process, ther...

Problems solved by technology

[0003] However, if the pipes are made into prefabricated pipes for installation during the shipbuilding process, there will be manufacturing errors in segmental production, prefabricated pipe production, and equipment positioning, which will cause a large number of prefabricated pipes to be inappropriate in size and need to be revised.

[0004] If all the pipes are made into on-site pipes during the ship construction process, the workload of on-site pipe calibration will increase, the labor intensity will increase, and the backward shift of the process will also affect the entire ship pipe installation cycle.
